10 Best Smart Toilet 2026 in the United States

The KOHLER NUMI 2.0 Comfort Height Smart Toilet is designed to offer a high level of comfort and advanced functionality. One of its standout features is the bidet functionality, which includes an adjustable stainless steel wand with options for water pressure, temperature, and spray shape. The heated seat and hands-free automatic lid and flush add to the convenience, ensuring a more hygienic and comfortable user experience. The deodorizer and self-cleaning functions, using UV light and electrolyzed water, help maintain cleanliness and freshness.

The motion-activated opening and closing of the lid, along with a quiet-close feature, prevent slamming and enhance ease of use. The dual flush system offers eco-friendly water usage options, with 0.8 or 1.0 gallons per flush, contributing to energy efficiency. The added height of the seat makes it more accessible for many adults, making sitting down and standing up easier. The compact, streamlined design ensures it fits well in various bathroom settings, and the elongated bowl provides extra comfort.

However, the requirement for professional installation may be a drawback for some users, as it adds to the overall cost and effort needed to set up the toilet. Additionally, being a high-end smart toilet, the price point might be steep for budget-conscious buyers. The KOHLER NUMI 2.0 is well-equipped with features that make it a strong contender in the smart toilet market, suitable for those looking for luxury and advanced functionality in their bathroom.

The TOTO NEOREST NX1 smart toilet offers several features that align well with what buyers typically seek in a smart-toilet category. It includes an integrated bidet with front, rear, and soft wash modes, providing versatile cleaning options. The dual flush system with 1.0 and 0.8 gallons per flush options promotes water efficiency, and the Tornado Flush system is designed for powerful, thorough cleaning.

The ceramic surface is treated with CEFIONTECT glaze to help prevent waste buildup, which supports easier maintenance. The EWATER+® technology uses electrolyzed water to keep the bowl cleaner, contributing to hygiene. The seat is plastic, and given TOTO's reputation, the build quality is expected to be solid, though the product’s relatively high weight (141 pounds) means installation may require professional assistance.

This model is suitable for users seeking a reliable, water-efficient smart toilet with quality bidet functions and enhanced cleanliness but may not include some advanced automation and convenience features that other premium models offer.

The TOTO Neorest LS is a high-end smart toilet that offers a full range of features designed for comfort and hygiene. Its bidet functions are versatile, including rear and front cleansing with options like oscillating and pulsating sprays, plus adjustable water pressure and temperature, making it very customizable for personal comfort. The heated seat with temperature control and automatic lid that opens and closes adds a touch of luxury and convenience. It also includes an air deodorizer, helping to keep the bathroom fresh.

The self-cleaning technology, featuring EWATER+ and PREMIST, helps maintain cleanliness by pre-wetting the bowl and using a special water treatment to reduce bacteria and grime, which is a great plus. The toilet uses a dual flush system with efficient water use (0.8 or 1.0 gallons per flush), supporting energy and water conservation goals. The remote control is illuminated and supports four user memory settings, making it easy to operate and personalize. The skirted design hides the trapway for easier cleaning and a sleek look.

The toilet is quite heavy and large, which might pose installation challenges in smaller bathrooms. Also, the seat is made of plastic, which some users might find less premium compared to other materials. It ranks high among bidet seats, though its popularity in broader home improvement categories is moderate, reflecting its specialized nature and higher price point. This smart toilet suits those looking to upgrade their bathroom with advanced hygiene features and modern convenience, though it requires some space and a willingness to invest in a premium product.
